Specification of Letters Patent.

Patented Nov. 5, '1918.

Application filed December` 29, 191'?. Serial No. 209,458.

To all whom t may concern.'

Be it known that l, JOHN Duonow, zt subject of the King of GreatBritain, and resident of 20 Fairmount avenue west, in thc 5 city anddistrict of Montreal, in the Prov ince of Quebec,4 in the Dominion ofOsinada, have invented certain new and useful Improvements inAccounting- Books, of which the followin is e specification.

'10 The invention re ates to improvements in accounting books asdescribed in the present .specification and illustrated in theaccompanying drawings that form part of the same.

The invention consists essentially of the novel means employed formarking certain places in the book for attention et definite times.

The objects of the invention are to fucilitate the managementof manyaccounts in a book, where attention `to the suine is required at varyingdates according to the terms and conditions of the several accounts, t0eliminate the losses and inconveniences incident to the lapses of.memory of the lclerk in regard to the obligations of customers andothers, to devise e new system of notin various accounts operable bycom1 parative y inexperienced clerks :ind always at hand, to thesuperior, and generally to provide a new form of book simple to open ateand cheaprto produce.

In the drawin Figure l is a view of a. book showing t e cover brokenaway and disclosing the calendar days of a long month on the inner sideof the beck cover.

Fig. 2 is a plan view of the sheet.

Fig. 3 is a. detail of a marker.

Fig. 4 is a plan view of a marker showing the gummed ends.

F1g..5 is a View showing the markers inv a lurality of colors.

ike numerals of reference indicate correslponding parts in each figure.eferring to the drawings, the shert Eil is perforated along en edgepreferably the bop edge to form a row oi' openings 52 comparativelyclose together and here shown as rectangular in shape, though they may60 be of any shape or size and in :my number, but they will likely be asshown one for each day of a long calendar month und three or four over..

The numerals running from 1 to 31 consecutively are rinted over theopenings 52 starting from eft to right, or from right to lci't us foundconvenient or in any order to suit the conditions of use.

'lhc sume set of numeruls l to 31 are mounted, printed, embossed orotherwise re produced on the inside oi the back cover 53 in alinenientwith the numerals on the sheet 52. Therefore when u page of the book ismarked by passing the marker 54: through one of the openings andsticking theA ends to ether therebeyond by means of the gomme ends 55,the suid marker points t0 the date on the cover row of numerals, as forexample, if it is desirabledto look up an account on the 7th dey of themonth, one of the markers 54:, formed of a short strip of paper or othersuitelile material, is insorted through the opening marked 'i' and stucktogether beyond the edge o the sheet. The protruding marker will thenpoint to the numeral 7 on the inside of the back cover and theaccountant will know that there is something to he donc to that accounton that day.

The markers fire preferably made of dif ferent colors to indicatecertain facts about the accounts marked. thereby enabling the merchantto .scc et .i glance without even opening the book, how many accountsare going had or getting into o. (lungerous state.

Many changes may be mode in this in vention as to its construction unduses with out departing from the spirit of the invention, so long :isthey are within the scope of the claims for nawclty following.

It muy be pointed out in regard to the colored markers that they mu y bevaried to such un extent ns to denote accounts revious and bad, :isnwntioned hereinbe ore, accounts wherein there are prospects for futuresale, instalments due, accounts collectable without the nid of a diary,1n fact in many respects eliminate the use of e diary.

What I claim is V 1. In a hook, :t plurality of leaves. each of saidleaves having a row of holes adjacent to an edge and a designation forthe majority of holes, a corresponding indicatpr havin the samedesignations und mar ers shaped to fit in seid holes and project, evondthe edge of the leaf. l
